Cisco 2611 NAT DHCP question

Hi all

I got a Cisco 2611 router and I am trying to set up a basic home network configuration. I set up interface e0/0 which connects to the cable modem to "ip addr dhcp" and e0/1 as DHCP server All this is working fine now.

Now I understand that I also need to setup NAT to be able to access the Internet from inside the home network. I saw some commands for NAT but I noticed that you have to specify the global IP address there. What if I get my IP by DHCP from the ISP? How can I specify that for NAT?

I guess I also need to set up some access lists to protect my network.

Any help is greatly appreciated.
